Hola estimats lectors, avui us parlarem de Plut\u00f3. Hem estat investigant sobre ell i ens ha semblat interessant compartir-vos-ho.<\/p>\n

Bona lectura \ud83e\udd13<\/p>\n

Plut\u00f3 (designaci\u00f3 de planeta menor Plut\u00f3) \u00e9s el planeta nan m\u00e9s gros del sistema solar.<\/p>\n

Va ser descobert per l’astr\u00f2nom\u00a0estatunidenc\u00a0Clyde Tombaugh el 1930, Plut\u00f3 va ser considerat el nov\u00e8 planeta del sistema solar.<\/p>\n

L’astr\u00f2graf\u00a0de l’Observatori Lowell\u00a0que serv\u00ed per descobrir Plut\u00f3 (en metall gris, el dispositiu fotogr\u00e0fic).<\/p>\n

Plut\u00f3 es compon principalment de roques i gel de met\u00e0, per\u00f2 tamb\u00e9 de gel d’aigua. El seu di\u00e0metre \u00e9s aproximadament dos ter\u00e7os el de la Lluna.<\/p>\n

Plut\u00f3 \u00e9s un objectiu dif\u00edcil per a l’exploraci\u00f3 espacial\u00a0a causa de la gran dist\u00e0ncia que el separa de la Terra, la gran\u00a0inclinaci\u00f3\u00a0de la seva \u00f2rbita (17 \u00b0) sobre l’ecl\u00edptica\u00a0i la seva massa tan petita.<\/p>\n

\"\"<\/a><\/p>\n

La\u00a0sonda espacial\u00a0New Horizons<\/i>, llan\u00e7ada el gener del 2006 per la\u00a0NASA, fou la primera a explorar el sistema plutoni\u00e0, el qual travess\u00e0 el 14 de juliol del 2015 a una dist\u00e0ncia m\u00ednima d’11.095\u00a0km, despr\u00e9s d’un viatge de 6.400\u00a0milions de quil\u00f2metres.<\/sup><\/sup><\/sup>\u00a0Durant el seu breu sobrevol, la\u00a0New Horizons<\/i> va mesurar i observar el sistema en gran detall.<\/p>\n

\"\"<\/a><\/p>\n

El descobriment de m\u00e9s d’un miler d’objectes transneptunians\u00a0en l’\u00faltima d\u00e8cada del segle\u00a0xx<\/span>, incloent-n’hi alguns de mida similar a la de Plut\u00f3, pos\u00e0 en dubte la seva condici\u00f3 de\u00a0planeta.<\/p>\n

Alguns cient\u00edfics proposaren reclassificar Plut\u00f3 com a planeta menor o objecte transneptuni\u00e0.<\/p>\n

B\u00e9! aqu\u00ed teniu un resum de la petita investigaci\u00f3 que hem fet, esperem que us doni peu a seguir buscant informaci\u00f3 sobre Plut\u00f3, nosaltres ho farem…\ud83d\ude09<\/p>\n
